Silica sand – applications in the glass and construction industry

What is silica sand?

Silica sand is a mineral raw material with an SiO₂ content of over 90%, often 95-99.9% in high purity grades. A hardness of 7 on the Mohs scale, high chemical resistance and melting point determine its wide industrial use.

Glass industry

Glass contains 70-74% SiO₂. Glass sand must meet stringent requirements: SiO₂ ≥99%, Fe₂O₃ <0.03% (colorless glass), granulation 0.1–0.5 mm.

Water filtration

Quartz sand with a fraction of 0.4–0.8 mm is used in pressure filters for the treatment of drinking and industrial water in accordance with the PN-EN 12904 standard.

Other uses

• Masonry mortars and plasters
• Moulding sands in foundry
• Silicate brick production
